Abstract

Background: The amount of electrical effects on the body's tissues are dependent of the voltage (voltage), the current srength (ampere), the resistance (dry or wet skin conditions), duration of contact with the source and extent of areas affected by contact. Electrcal trauma is one of the three biggest causes of death. This mortality can occur rapidly (direct effect) or slow (complications). This study aims to prove the association between amount variation of alternating current (AC) elecricity and time of death wistar rats.
Methods: This study is a laboratory experimental design with the one-shot case study design that uses guinea pig as an experimental object. 24 wistar rats were taken by simple random sampling. They were divided into four groups: group 1 exposed to electric currents 1-30 mA, group 2 exposed to electric currents 31-60 mA, group 3 exposed to electric currents 61-90 mA, group 4 exposure to electric current 91-120mA. . After the adaptation period of 7 days, exposure to electric current conducted later observed strong influence of large electrical current to the death of rats. Statistical analysis was conducted by using Spearman test.
Result: There was significant negative correlation between amount variation of alternating current (AC) electricity and time of death wistar rats (rho = -0 675, p = 0.000).
Conclusions: There is a relation between amount variation of alternating current (AC) electricity and time of death wistar rats. The greater the exposure to electric current, the faster it's death.
